Bass trapping (done properly) is going to fill 50% of that room.
I recommend forgetting bass traps and controlling the bass output (not overloading the room). Getting monitors with front facing ports, an absolute maximum of 5 inch drivers, a small high quality subwoofer such as an Eve Audio 6 or 7 inch woofer model, and treat 50% of the walls with 75mm (minimum) to 100mm deep acoustic foam tiles. Don’t buy cheap ones they’re shit.
The construction of the walls floor and ceiling can have a massive impact on the sound too.
The room is almost square, which could be an issue (more standing waves).
If you really want SOME bass traps then I would do top two corners of the room (against the ceiling), so they’d be triangle shaped and wouldn’t take up floor space. They’d probably be like a metre across in size though so would feel gigantic in there.
If you do decide to bass trap then research the proper sizes for actually being effective instead of buying off the shelf crap which is often way too small to be effective.
